The circumstances that lead to false imprisonment charges can vary but can include the use of restraints to keep an individual bound in place as well as efforts to prevent movement by confining them to a room, vehicle, or other space.
There are situations where imprisonment, even by a civilian, is considered lawful. For instance, if an individual restrains someone who has carried out a robbery or violent offense, the restraint may be considered justified. False imprisonment can also occur when a parent knowingly restrains their child and thus infringes on their freedom of movement in an unlawful way.
If an individual knowingly and unlawfully restrains an individual who is 18 years or older, the offense is considered a misdemeanor in the second degree. If, however, the individual is under the age of 18, the offense of upgrade to a felony of the second degree.
